syncopated.

here. comments are funny too. "not so loud, i've got a headache."

today i learned that there's no such thing as an x squared distribution, but we have something called a chi squared distribution. greek algebraic letters, "... that he used against unarmed civilians in order to broadcast a message of hate."

in order to perform testing of goodness-of-fit, students have to calculate the expected frequencies from the various distributions that were covered in a previous chapter. thus they must be well-versed in all these distributions. students tend to be confused by the testing of mean in the previous chapter, with the testing of fit in this chapter. students can also have problems with constructing contingency tables. overall, a rather tedious chapter.

i've never seen anything like it.

a plea for help crossing the river.
